Metal-made pallet

ABSTRACT

A metal-made pallet includes a top board, a plurality of lower boards and a support part connected between the top board and the lower boards. The support part has recessed portions and protrusion portions. The recessed portions are fixed to the lower boards and the protrusion portions are fixed to the top board according to the desired specifications. The pallet is strong, reusable and easily to be fabricated. The metal-made pallets can recycle and reuse and are successfully avoided from the insect problems, furthermore has the environmental protection effect.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a metal-made pallet which is strong,easily to be fabricated and friendly to the environment.

2. Description of the Related Art

A conventional pallet 1 is disclosed in FIG. 1 and generally includes aplurality of parallel elongate boards 12 and support legs 11 which areperpendicularly connected to the elongate boards 12 by nails 13 to forma rectangular pallet 1. The support legs 11 are separated and put on theground and goods 14 is put on the boards 12. A certain height of gap isdefined between the boards 12 and the support legs 11 so as to keep thegoods 14 away from the ground and humidity. The gap is suitable for theforklift truck to raise the goods 14.

However, there are several shortcomings for the conventional pallet 1,which are:

-   -   1. The boards 12 and the support legs 11 are wood material which        is easily to be rotten and damaged. Once the boards 12 and/or        support legs 11 are damaged, they cannot bear the loads as        desired and could lead a dangerous result.

The damaged wood boards 12 and legs 11 cannot be re-used.

-   -   2. The wood boards 12 and legs 11 might have bugs or insects        lived therein which might immigrate together with the        transportation and becomes invaders for different countries or        areas and the invaders of species might be harmful to the forest        in those countries or areas. Therefore, most of countries        require the pallets 1 to be fumigated before use and this takes        a lot of time and cost.    -   3. The source of boards 12 and legs 11 are get by cutting trees        and the demands of the trees hit the environment of the earth.    -   4. In order to save the woods, the manufactures has to sort the        wood to cut into similar or required size of boards and this        also increases the cost of time.

The present invention intends to provide a pallet that is made by metalwhich are welded with each other.

SUMMARY OF THE INVENTION

The present invention relates to a metal-made pallet which comprises atop board, a plurality of lower boards and a support part which isconnected between the top board and the lower boards. The support parthas recessed portions and protrusion portions. The recessed portions arefixed to the lower boards and the protrusion portions are fixed to thetop board.

The present invention will become more obvious from the followingdescription when taken in connection with the accompanying drawingswhich show, for purposes of illustration only, a preferred embodiment inaccordance with the present invention.

BRIEF DESCRIPTION OF THE DRAWINGS

Other features and advantages of the present invention will becomeapparent in the following detailed description of the preferredembodiments of the present invention, with reference to the accompanyingdrawings, in which:

FIG. 1 shows a conventional wood pallet with goods put thereon;

FIG. 2 is an exploded view to show the pallet of the present invention;

FIG. 3 is a cross sectional view of the pallet of the present invention;

FIG. 4 is an exploded view to show another embodiment of the pallet ofthe present invention, and FIG. 5 is a cross sectional view of thepallet of the present invention in FIG. 4.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention relates to a metal-made pallet. But below onlyperforms take the steel as the example to explain.

-   -   Referring to FIGS. 2 and 3, the pallet 2 of the present        invention is constructed by steel boards and comprises a top        board 21, a plurality of lower boards 22 and a support part 23        which is connected between the top board 21 and the lower boards        22. The support part 23 has recessed portions 231 and protrusion        portions 232 which are located in an alternative arrangement to        the recessed portions 231. The recessed portions 231 are fixedly        welded to the lower boards 22 and the protrusion portions 232        are fixedly welded to the top board 21. The two sides of the        support part 23 are bent inward to form two respective        connection surfaces which are fixed to the top board 21. A        plurality of steel columns 24 extend from a top of the top board        21 and each column 24 is bent to have an L-shaped cross section        by a steel board 241.

The top board 21, the support part 23 and the lower boards 22 are cutfrom a steel board by machine according desired specifications and thesupport part 23 and the columns 24 are further bent into desired shape.The top board 21, the support part 23, the lower boards 22 and thecolumns 24 are welded with each other for be the pallet 2 of the presentinvention. The goods 4 is put on the top board 21 and positioned betweenthe columns 24. The gaps 233 in the support part 23 between the topboard 21 and the lower boards 22 are cooperated with fork lift truck.

FIGS. 4 and 5 show another embodiment of the pallet 5 which includes atop board 51 having two protrusions 511 extending from two ends of anunderside thereof, a plurality of lower boards 52 and a support part 53which is connected between the top board 51 and the lower boards 52. Thesupport part 53 has a recessed portion 531. The underside 532 of therecessed portion 531 and the two protrusions 511 both are fixedly weldedto the lower boards 52. A plurality of L-shaped columns 54 extend from atop of the top board 51 and are made by metal boards.

The pallet of the present invention be made by steel boards so that thepallets can be made by machine within a short period of time. Thepallets do not have the shortcomings happened in the conventional woodpallets such as problems of insects, and are friendly to theenvironment. The steel boards are strong and reliable and can be reused.

While we have shown and described the embodiment in accordance with thepresent invention, it should be clear to those skilled in the art thatfurther embodiments may be made without departing from the scope of thepresent invention.
